HYDROCA-RBON-BURNER'.

srEcIEIcATIoN forming part of Letters was 1\l'o. 614,030, dated November s, 1898;

Application filed August 19, 1895.

Be it known that I, GEORGE H. SHERMAN, a citizen of the United States, residing at Detroit, in thecounty of Wayne and State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in 'the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in hydrocarbon-burners; and it consists in a certain construction and arrangement of parts, as hereinafter fully set forth, the essential features of which being pointed out particularly in the claims.

The object of the invention is to produce a burner of this class in which provision is made for facilitating a free and rapid vaporization of the hydrocarbon fuel and the mixing of air therewith in such quantities as to afford perfect combustion, and in which the arrangement is such as to combine effectiveness of operation with durability and cheapness of construction, which object is attained by the device illustrated in the accompanying drawings, in which- Figure 1 is a perspective View of my improved burner. Fig. 2 is a central vertical longitudinal section through the same. Fig. 3 is a transverse vertical section through one of the combustion spaces of the burner as on line 3 3 of Fig. 2.

This improved burner is made, preferably, of cast-iron, because of its cheapness and durability, is cast integral, and consists of the solid sides A and the interposed sinuous wall B, connecting said sides. This wall is continuous and by a series of sinuous bends crosses the burner-space vertically from end to end thereof between the sides A, forming a series of approximately parallel walls dividing the burner-space extending from the top to the bottom. These walls are perforated or provided with a series of successive slits a, by sawing downward from the top through the entire series thereof. Said saw-kerfs do Serial No: 559,718. (No model.)

not extend through the base of said walls, but terminate slightly above the lower bends b, which form intermediate troughs or channels 0, extending transversely of the burner between the sides A at the base of the slotted vertical wall, but integral therewith. Oommunicating with these channels, atone end thereof, is a continuous gallery 0, extending along the base of one of the sides A and into which said channels open, as clearly shown in Fig. 3. Connected with said gallery 0 is a supply-pipe E, which conveys the hydrocarbon fuel to the burner, said fuel flowing along said gallery and into the channels 0. By the employment of this continuous dividing-wall crossing the burner-space by return-bends a series of combustion spaces or chambers D are formed above the channels 0, open at their upper ends, and a series of interposed airspaces F, open at the bottom and communicatting with said combustion-chambers through the slots or apertures a in the dividing walls.

For the purpose of supporting and holding the upper ends of the slotted Walls or partitions an aperture is formed longitudinally thereof, through which is passed a rod (1, the ends of which are riveted in the sides A, whereby the divided upper ends of the slotted walls are prevented from separating, and said rods closing the slots in said walls at the apex of the upper bends deflect the air rising in the space F into the combustion-chambers on each side at the upper ends thereof and more perfectly support combustion at this point.

At each end of the burner 'is a hood H, depending from the outwardly-turned ends of the end walls and which meets the extended ends A of the sides A, forming an air-space F between said hoods and the end walls of the burner, through the apertures of which the air is deflected by said hoods into the adjacent combustion-spaces.

In the operation of this improved burner the hydrocarbon fuel flows through the gallery 0 and into the communicating-channels G, in

' which it quickly vaporizes and is ignited, the

upward by the caloric current, as indicated by the arrows 1. The upward passage of said current draws the air rapidly from the spaces F through the slits a in the dividing-walls, as indicated by the arrows 2. This mixing of the air with the vapor within the chambers D insures perfect combustion, the flame burning freely from the open end of said chambers. As the burner becomes heated the vaporization or the hydrocarbon fuel is accelerated and the efficiency of the burner increased.

This formation of the burner enables it to be cast integral, with the exception of the hoods or deflectors H, and by sawing transversely of the dividing-walls to form the slits or perforations therein a burner of great durability is produced which may be cheaply constructed.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A hydrocarbon-burner consisting of the opposed sides, the continuous slotted dividing-wall extending between said sides formed integrally therewith and crossing the burnerspace by a series of return-bends, dividing said space into interposed airand vapor chambers which communicate through the slots in said walls.

2. A hydrocarbon-burner consisting of the opposed sides, the slotted integral dividingwall extending between said sides and crossing the burner-space by a series of return= bends dividing said space into interposed air and vapor chambers, the lower bends of said wall forming transverse channels at the bottom of the Vapor-chambers, as set forth.

3. In a hydrocarbon-burner, the combination of the sides, the slotted dividing-wall extending between said sides and dividing the burner-space by a series of return-bends forming interposed vapor and air chambers which communicate through the openings in said wall, the channels at the base of the vaporchambers, the gallery formed integral with the burner communicating with said channels and connected with the fuel-supply and the hoods at the ends of said burner.

4. In a burner, the combination of the sides, a dividing-wall between said sides formed integral therewith and crossing the burnerspace by a series of sinuous bends forming interposed air and vapor chambers, said walls being provided with openings formed bya series of slits extending vertically downward from the upper bends thereof effecting a communication between said chambers, the lower bends of said wall forming channels at the base of the vapor-chambers, and the tie-rods passing longitudinally of the upper bends of said wall secured in said sides.

In testimony whereof I atfix my signature in presence of two witnesses.

GEORGE II. SHERMAN.
